Traditionally God has been considered absolutely simple. Some contemporary philosophers argue that this means that God is His attributes and hence is mere quality, and that all the divine attributes name exactly the same quality, which is incoherent. However, the contemporary debate misunderstands the tradition. God is not quality, He is act. Analogies from human experience can minimize the initial implausibility. There are worrisome corollaries to this doctrine, the most troubling being that God's nature is somehow dependent on the choices of His free creatures. This conclusion, though radical, is not as shocking as it appears.
